Full Details
Washington Governor signed HB 2320 into law on March 24, 2026, making Washington the state with the most expansive 3D printing gun legislation in the country.
The law closes what legislators called "technological loopholes" by directly regulating the digital blueprints (CAD files, STL files) that enable ghost gun printing — not just the physical firearms themselves. This is a significant expansion beyond previous state laws that only regulated the physical objects.
Key provisions include prohibiting the use of 3D printers to manufacture unserialized firearms and regulating the distribution of digital files specifically designed to produce functional firearms.
For hobbyists who print non-firearm objects, this law has no direct impact. It targets the specific use case of printing unserialized, untraceable firearms.
